As there is huge interest from the UAV community in using light weight and reliable satellite communication the http://mavlab.tudelft.nl/ made the iridium development open-source so the UAV community can benefit from this achievement.

@Earthpatrol. So I have a Lisa M and 2.4 xbee telemetry radios and I am determined to set this all up in a Bixler 3. Paparazzi seems to have lost a lot of its base. The last RCGroups posting was 2014 that I could find and I can see no current airframes posted on the wikki -- maybe I will have to add mine. Yet I can still see work is being done on github. The biggest issue is the lack of a more friendly Mission Planning app or application. I do not mind 'compiling sketches' for missions though but I think it may deter others.
